I was just perusing that site! (search for “G063” at link below):
I had assumed Roger Romage was the only guy replicating them (in limited runs for several years now), but that site does seem to suggest possibly otherwise (that or the wording simply wasn’t clear).
The Roddenberry site does also say they are “copied directly from an original prop”, which surprised me. I had assumed Romage had them made based on close examination of screen shots only.
Regardless, I’m sure I’ll be delighted with them. They were a bit more expensive than I hoped based on the “Las Vegas” pricing…but like “kertratz” said, they are quite lovely, and now I get a “certificate of authenticity”.
